Be it known that I, Josemi C. REGAN, a

kcitizen of the lvnited Statesof America. residing atNew, Britain. Connecticut, have inv vented a new and useful Improvement in Electric Switches, of which the following is My invention relates particularly to iiiclosed switchesv and particularly switches having` external operating handles, for in stance, of the` type .shown in the Sutherland .lateiit #1.271.520

y n Iii some ofthese constructions it is quite awkward and in fact diflicult to pack these switchcsfor shipment on account of the projecting handle. and iii fact these handles are sometimes broken intraiispoi'tation so that the switch'arrives in a defective condition.

. To avoid these troubles, I propose. to prol vide a detachable handle, and it is the niain object of this invention to provide a construction which may be operated in thelusual way but in which the handle maybe shipped detached and may be readily attached when necessary. It is a further object to make thisconstruction at a reasonable cost and such that the parts can be assembled byanyone without experience and withoutV the pos -sibility of error. i

It is-the further object to insure the rigidity and periiianeiicy of the connection.

'lliese objects'are attained by the construction comprising` a huh which is mounted to rotate in tlie switchbox and connected iii any satisfactory way with the internal switch inechanisin. The handle'isl preferably entirely outside of the box. The hub and haiidle are provided with interfitting bosses and shoulders and connected by a single screw.

Figure'l is a side view of an inclosed switch eiiibodyiiigthe improvements of my invention showing the'haiidle in full lines in one position and in dotted lilies in another position. y

ner.

The liub 12 which'isconnected to the'interior switch mechanism is rotatably inounted in one side ofthe'box and inthe form shown provided with a tiange 13..

The handle 14 is of any suitable shape and is secured to the hub by a screw 15 which passes through the aperture land is seated in the threaded V*socket* 17 in the hub.

The hub with a boss 18 which surrounds the screw socket and fits into a recess 19 in theliandle.

The hub is also preferably provided with one or more lugs suoli as 20 and 21 which Pa*tentedAnga 19, 1919.; l Application sied Aprii 1o, '1919. seriai Nofesseea i suitable type connected in any suitable man- 6o itself is preferably provided fit into recesses 22 and 23 ninthe handle so 7o as to cause the handle and hub to be connected without the possibility of independi ent rotary movement.. To afford an even bearii'ig the face 24 of the hub may be iin# ished andthe face 25 respondingly finished. The lugs 20 and 21 provide transverse shoulders such as-26, 27 and 28, which fit against corresponding shouldn-S29, 30 and 3101i the liandle'so as of the handle cor` 75 to transmit 'force from thehandle to he 80 liuband the switch member contained in t e boze.

Iii the form of construction shown in Figs. 5 andY G the' hub 12 is provided with a flange 13', a screw socket 17 and a boss 85 18'. The handle 14 has a recess 19 for the boss and the a` screw 15. In this case the hub has but' ay single transverse shoulder 32 which coacts with a corresponding shoulder 33 onl 90 the handle. In both forms ofconstruction,

l'iowever. it will be noted that there is a transverse shoulder located eccentrically or at one side of the center of tlieliub so as to provide a substantial leverage for tiansiiiitting power from the handle to the hub and the interior switch mechanism.

The handle .may be provided with a slotted projection 34 adapted to be secured to the stationary slotted projection 35 onthe 100 side of the box, for instance, by means of a padlock 36.' This not only prevents operation of the switch, but prevents removal of the handle.

I claim:

1. ln an electric switch construction, a switch box,- a huh mounted ,in the side thereof and provided with a central boss part-s are secured togetlfer byr and a shoulder'eccentric thereof, a handle' provided with a recess `for said boss and -a'shoulder co-acting with tlie'shoulder on said hub, and means for securing said handle to said hub.

- 2..'In an electric switch constructioii,the combination ofa switch box, a hub having one end exposed at one side thereof, said 'hub having a central screw threaded recess 'A and a shoulder at one side thereof,a handle having a corresponding co-acting shoulder and an aperture, and a screw passing through the aperture of the handle and "seated in the threaded recessl in the hub.

3. In a switch construction, the combination of a switch box, a hub having a central threaded recess, a boss around th(` entrance thereto and a transverse shoulder adjacent 4. In an electric switch construction, the

combination of a switch box, a hub journaled' in the wall'of saidl switch box, and provided with -an external flange to hear against the'fa'ce'of said wall, and with an. external screw seat, a detachable handle en'' gageable with the exposed face of the hub., the engaging faces of said handle and hub havincV interlockin shoulders and a screwl entered through the handle into engage nient With-the screw seat in the hub. 5. In an electric switch construct-ion, .a

v.switch box, a hub journaled in the wall ofl said switch box and having an exposed outer end provided with a screw seat and with projecting lugs at opposite sides of said screw seat, a detachable handle engageable with said exposed face of the hub and provided with shoulders to engage with the pro]ecting lugs on the hub, and a screw adapted to be entered through the handle' into engagement withthe screw seat inthe hub. i Y,
